nearly doubled in 2-months - but Why?
As I see it the underlying investments haven't changed, true the finances are altered but the money they have gained was at the expense of stock so I don't understand, other than some logic that says if some folk are prepared to pay double the current price - then the current price needs to be raised.

Er, sorry I don't think so. For institutions it is difficult to trade at Market Price since they want large numbers (or not at all) - so it is likely they pay the extra to buy-in when they think there is something good abouut to happen - - - but Sigmas tranck record is not exceptional - and it moves slowly, at the same speed as their better investments (er, less a bit for the bad ones).

Maybe wait for this froth to subside. Currently c.58 pence after a recent 64p peak
